OIL-ENGINE.

Specification of Letters Patent.

Patented Sept. 23, .1913.

Application filed September 14, 1910. Serial No. 581,975.

To all whom it may concern Be it known that I, MAX RionAnn Mn'r'rr, engineer, a subject of the King of Sweden, residing at Falun, Sweden, have invented new and useful Improvements in Oil-Engines, of which the following is a specification.

My present invention relates to a device, by means of which in gas or oil engines with one or several cylinders it will be possible to regulate the moment of introduction of the air or the combustible or both during the run of the machine. In such machines it has been proposed to use instead of the known rotating cam disks reciprocating organs, either consisting in reciprocating bars or in organs oscillating on a shaft, the said reciprocating; or oscillating organs being provided with cam surfaces.

My invention consists in the said reciprocating or oscillating organs being connected with the driving means by means of an adjustable body, which, when adjusted, causes the said reciprocating 0r oscillating or rocking organ being displaced, so that the moment of introduction of the air or the combustible or both into the cylinder will be changed.

The reciprocating or oscillating or rocking organ can be provided with more than one cam surface, cooperating with one and the same organ actuating the valves or the pump. If more than one cam surface be arranged, the organ must be adjustable in such a way as to bring the one or the other cam surface in cooperation with the valve or pump actuating organ.

By arranging a plurality of cam surfaces on the cam carrying organ, it is possible to actuate from a single cam carrying organ the pump and one or several valves. It will for instance be possible to actuate from the said organ an air valve, which in the moment when the organ is in such a position as corresponds to a preignition caused by the combustible being introduced at an earlier moment, will introduce such a quantity of. air in the cylinder as to prevent the piston from passing the dead point, whereby a much better and more etlicient reversing of the engine is attained than is possible with the usual means.

My invention is shown on the accompanying drawings.

Figure 1 is a view in side elevation of a two cylinder engine embodying my im provements. Fig. 2 is a plan view of a two cylinder engine embodying a modified form of my improvement. 3 and 4t show in side elevation two different embodiments in connection with a. single cylinder engine. Fig. 5 shows a detail of Fig. l. Fig. 6 shows a part of the cam hurrying bar with two cam surfaces.

In Figs. 1. and 2 the governor shaft Z) of the engine a is driven from the engine shaft by means of a screw transmission f or in any other suitable way. The governor 0 acts by means of the levers (Z and connecting link 0 upon the regulating shaft 0, which is movably arranged in the direction of its length. ()n the shaft 7) there is arranged an eccentric working on the reciprocating bar 7 by means of the rod 71., said bar 77 being parallel to the shaft (2. The bar is provided with cam surfaces 7cn against which the rod Z abuts by means of the roll m. ()n the reciprocating movement of the bar 2' the rod Z will of course receive a reciprocating motion in the direction of its length. The rod Z is directly or indirectly connected with the oil pump or the admission or exhaust valve for the air or the oil, actuating the same when moving. It is clear, that the cam surface 7: can be arranged on the rod [and the roll m 011 the bar 2'.

In order that it may be possible to adjust the cam surface 7.1, during the run of the engine, thereby regulating the motion of the rod Z and the valve connected with it, the bar 2' in the modified form shown in Fig. 2 is connected with the eccentric in such a way as to make it possible to adjust the position of the rod 2' relatively to the eccentric g during the run of the motor. According to the embodiment shown in Fig. 2 this is performed by the following device: The bar 71 is provided with a disk 0, wherein a recess 7) is arranged. In this recess, which is inclined to the direction of the length of the bar 6, there is inserted a pin, arranged on the red It. By means of the wheel 0* and the rod .9 the said pin can be moved in the recess 7), and by such a motion the bar i and the ec centric will be moved against or from each other. and the time at which the motion of rod Z is reversed will be thereby changed.

In order that it may be possible to regulate the quantity of the oil and not only the moment of introduction of the air or the oil, the rod Z, connected with the oil pump, is

provided with a projection t, cooperating with the inclined surface a of the shaft 6.

shaft 6 and thereby the quantity of oil, in-

troduced in the cylinder, will be varied. In order that it may be possible to regulate the action of the inclined surface by hand, the said surface a can be formed on a longitudinal adjustable key 1;, movable on the shaft 6, as shown in Fig. 5. a: is a screw, by means of which the position of the key Q; can be adjusted.

The embodiment shown in Fig. 3 differs from the one described above, by the eccentric 9 being arranged on the engine shaft y and by the shaft .6 being omitted. The rod h is connected with a bell crank lever Z, rocking on the pin 3, arranged on a rod 2, which is adjustable in its length direction by means of the wheel. r. The bell crank lever Z is in its other end provided with a pin 4,

inserted in a recess 5 in'the cam carrying bar 2', which acts upon the rod Z in the same way as in Figs. 1 and 2. The wheel 1 being turned, the pin 8 will change its position, whereby the bar 2' will be acted upon by the bell crank lever Z at another moment than before.

According to the embodiment, shown in Figs. 4 and 5 the rod h acts upon a rock lever 0 provided with a nave 7, freely turning upon the pin 6, forming the end of the bar 2'', which is, as will be described hereinafter, given a rocking motion in the guide ways 8. On the bar 2" a rock lever 0 is arranged, cooperating with the rock lever 0 by means of the part 11 and besides the said bar 2' is provided with a nave 9, where on the cam surface n is arranged, cooperating with the rod Z by the intermediate rollm. On the rotation of the eccentric g the rock lever 0 will obtain a rocking motion, which 'is submitted to the bar 2" by means of the part 11 and therock lever 0 In this way the cam surface will obtain a rocking and the rod Z .a reciprocating motion in the direction of its length. 7 V

In order to make it possible to adjust the cam n during the run of the engine, the rock levers 0 ando are provided with inclined grooves 39 and p wherein pins 10 and 10, projecting from the part 11, are inserted. The said part 11 is secured to the rod 8, which can be adjusted by means of the wheel 7. WVhen said wheel be turned, the rod 8 is moved in the direction of its length, whereby the part 11 is moved be tween the rock levers 0 and 0 On account ofthe pins 10 and 10 projecting into the grooves 79 and 72 the levers 0 and 0 will by the said motion of the part 11 be turned in relation to each other, which causes the bar '2' to change its position in relation to the eccentric g. The'shaft e is in this embodiment constructed quite as is-shown in Figs. 1 and 2. only that the key '2) in this embodiment is slidable in its longitudinal direction. The key for this reason is pro vided with a rod 12, slidably arranged in the guideway 13, wherein it can be secured by means of the screw 50. The bar 2", of course, can be provided with more than one cam" surface, in which case it must be made adjustable not only'in the direction of its length, but also in a direct-ion forming an angle thereto. 'Fig. 6 shows such a bar 2' carrying two cam surfaces and is, for a common organl and having a reciprocating motion in its length direction. The bar 71 is. adjustable in the direction of its length, for instance by the aid of such devices as shown in Figs. 13, but it must besides that be turnably arranged, a". 6. arranged in such a way as to be adjusted in a direction perpendicular to the direction of the length of the cam surfaces. means of adevice according to the one shown in Figs. 4 and 5 or by any other.

This may be done by Y the cam surface in relation to said driving organ during the run of the engine, that the situation, but not the length of the moving path of the cam is adjusted during the run of the engine. I

3. In oil engines, in combination, a cam carrying organ having zi -reciprocating motion, a driving organ for giving the said cam carrying organ this reciprocating motion and adjustable means for adjusting the situation of the moving path of the cam, thereby, however, maintaining the length of said moving path.

4;. In oil engines, in combination, a cam carrying organ having a rectilinearly reciprocating motion, means for giving the said cam carrying organ this reciprocating mo tion and adjustable means between the cam carrying organ and the drivin means for adjusting the moving path of the cam, during the run of the engine, thereby, however, maintaining the length of said moving path.

5. In oil engines, in combination, a cam carrying organ having a reciprocating motion, a driving organ for giving the cam carrying organ this reciprocating motion and an inclined groove between the cam carrying organ and the driving organ, connected with the one part and cooperating with a projection from the other part.

6. In oil engines, in combination, a cam carrying organ, having a reciprocating mo tion, a driving organ for giving the said cam carrying organ this reciprocating motion and rotatable adjusting means, inserted between the cam carrying organ and the driving means and adapted for adjusting the situation of the moving path, thereby maintaining the length of said path.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
